WebApr 14, 2024 · The rapidly growing number of space activities is generating numerous space debris, which greatly threatens the safety of space operations. Therefore, space-based space debris surveillance is crucial for the early avoidance of spacecraft emergencies. With the progress in computer vision technology, space debris detection using optical sensors … WebIn dataset-aware focal loss, negative samples are not shared across different datasets. So loss values of negative samples from face dataset are set to zero when calculating focal loss for the class pedestrian. Positive samples from different datasets are generated together according to their own ground truth labels, so there exist no conflicts ...
